+**Blur** is a visual phenomenon where the sharp edges and details of an object become indistinct, leading to a hazy or fuzzy appearance. It can arise from a lack of [Focus](/wiki/Focus) in optics, rapid motion, or as a deliberate artistic effect in [Photography](/wiki/Photography) to convey mood or speed. This softening of an image often alters its perceived clarity.
